Radiometric, or nuclear, measurements are made using a radioactive source and a detector. Radiometric sensors have no moving parts, and each component mounts external to the vessel without any contact to the process material being measured or exposure to operational pressures or temperatures.

This low-maintenance, non-intrusive technology provides critical level, density, weight, and mass flow measurements in refineries, petrochemical plants, mines, paper mills, and a number of other heavy industries. Radiometric sensors deliver reliable, long-term measurement solutions where other sensors struggle or fail.
